2. november 2017: What happened at the beginning of the Universe? It’s a question astronomers have pondered for a long time. Whilst we can’t actually travel back in time, astronomers are able to see into the past and observe galaxies and stars that were made when our Universe was still very young. Because light travels at a finite speed, the further away an object is, the longer its light has taken to reach us — so we see distant objects as they were in the past. To see the most distant celestial objects astronomers use some of the world’s most advanced telescopes, many of them unique — like ALMA. ESOcast 135 describes how ALMA enables astronomers see into the past and learn more about what our Universe was like when it was young.

31. oktober 2017: Den tredje gaskæmpe - en hot Jupiter - i kredsløb om en M-dværgstjerne[1] er fundet med Next Generation Transit Survey (NGTS) instrumentet på ESOs Paranal Observatory i det nordlige Chile. Stjernen har fået navnet NGTS-1 og planeten tilsvarende NGTS-1b. De to første varme gaskæmper var Kepler-45b og HATS-6b. NGTS-1b er den største og tungeste af de tre. Den har en radius på 130% og en masse på 80% af Jupiter i vores eget Solsystem. Danskbaseret exoplanetjæger er også begejstret. NGTS består af et anlæg med 12 stk 20-centimeterteleskoper, som ser efter de små dyk i en stjernes lysstyrke, som kommer når en planet i kredsløb om stjernen passerer ind foran den (- en transit, svarende til en solformørkelse, men meget længere væk), og blokerer for noget af dens lys. Da først NGTS-1b var fundet, blev dens eksistens bekræftet med observationer fra ESOs La Sillaobservatorium: fotometriske observationer med instrumentet EulerCam på ...

16. oktober 2017: ESO’s telescopes have observed for the first time the visible counterpart to a gravitational wave source. Marking the start of a new era of multi-messenger astronomy, this rare event was captured in extraordinary detail. The observations unveil a high-energy event, known as a kilonova, that can finally be connected to the merging of two neutron stars, stellar remnants that emit gravitational waves as they spiral towards each other and then collide in a spectacular explosion. ESOcast 133 describes what was observed by ESO’s telescopes in Chile, how telescopes around the world found the kilonova, and what astronomers have learned about this newly observed astronomical phenomenon.

12. oktober 2017: How can we find out more about the origins of life on Earth? Well, we can leave Earth behind and instead look out into the Universe. The atoms that make up our bodies can only be made in the high pressure and high temperature environments of stars. When stars end their lives, sometimes in spectacular supernova explosions, the atoms that they made within them are spread across space where they form the next generation of stars and planets. In the clouds from which stars and planets form, the atoms bond together to form molecules. ESOcast 132 describes how ALMA can be used to observe many different molecules throughout the farthest reaches of the Universe, including some that are needed for life, .

2. oktober 2017: Størst er vel bedst, ihvertfald når det gælder teleskoper, som skal observere det enorme Univers? Ikke nødvendigvis. ALMA er det største jordbaserede anlæg til observationer af radiobølger fra rummet, men anlægget består af 66 forholdsvis små flytbare antenner, som kobles sammen, så de fungerer som eet enormt radioteleskop. De billeder, som det samlede anlæg modtager svarer til, hvad man ville få ud af et teleskop med en diameter på 16 kilometer. ESOcast 130 fortæller hvorfor astronomerne er vilde med at bruge ALMAs enorme størrelse og effektivitet, og hvordan topteknologien giver os observationer, som er banebrydende i præcision og kvalitet. Alle kan abonnere på ESOcasts via iTunes, hente fremtidige udgivelser på YouTube eller følge os på Vimeo. Der er også mange andre ESOcasts klar til at downloade og nyde. Vi vil gerne have hjælp til at få oversat og tekstet vore ESOcasts flere sprog, og til at oversætte denne video på ...

15. september 2017: MATISSE, the Multi-AperTure mid-Infrared SpectroScopic Experiment, has passed a suite of initial tests conducted at the Observatoire de la Côte d’Azur in France and will now be transported to Chile for integration into the Very Large Telescope Interferometer (VLTI) at ESO’s Paranal Observatory. MATISSE is a four-way beam combiner, meaning that it will combine the light collected by up to four of the eight telescopes that make up the VLTI, and perform both spectroscopic and imaging observations. In so doing, MATISSE and the VLTI will together possess the imaging power of a telescope up to 200 metres in diameter, depending on the telescope configuration, and will be capable of producing stunningly detailed images. MATISSE will observe infrared light from the L-band to the N-band, which lie between visible and microwave wavelengths in the electromagnetic spectrum. The instrument is designed to contribute to several fundamental research areas in astronomy, focusing on ...
